ifx_affected_rows

Get number of rows affected by a query
(PHP 3 >= 3.0.3, PHP 4, PHP 5)

int ifx_affected_rows ( intresult_id )

Returns the number of rows affected by a query associated with
result_id.

For inserts, updates and deletes the number is the real number
(sqlerrd[2]) of affected rows. For selects it is an estimate
(sqlerrd[0]). Don't rely on it. The database server can never
return the actual number of rows that will be returned by a
SELECT because it has not even begun fetching them at this stage
(just after the "PREPARE" when the optimizer has determined the
query plan).

Useful after ifx_prepare() to limit queries to
reasonable result sets.
